Problem conclusion

Customer resolved problem by correcting CheckSum error in their
Perl script.
APAR fix only delivers nominal enhancement to Universal Agents's
reaction to bad data arriving on SNMP trap listening socket.
This APAR "fix" added a counter that checks for 5 consecutive
recvfrm() failures and if so then original Universal Agent
behavior of exiting from loop on recvfrm() failure and
terminating SNMP trap 'listening' thread is carried out - this
APAR can not fix a customer's code.
The fix for this APAR is included in the following maintenance
vehicle:
| fix pack | 6.2.3-TIV-ITM-FP0003
